Here are the steps in screenshots to collect the dump file. Typically a 800+ MBytes file called WmsShell.DMP will be generated, please zip it so it's much smaller and easier to transfer, then upload to any free file share services such as Microsoft's skydrive.live.com and email its link to us.
If none of the stations are responding, you will need to remote login from another system via RDP as an administrator to collect the dump file.
